Serum albumin, subjective global assessment, body mass index and the bioimpedance analysis in the assessment of malnutrition in patients up to 15 years after liver transplantation. Clin Transplant 2011: 25: E396–E3400. © 2011 John Wiley & Sons A/S. : Background: The subjective global assessment (SGA) or the body mass index (BMI) is used to determine the nutritional state after LTX. Bioelectrical impedance analysis (BIA) is used as tool to determine body composition by nutritional care professionals. Methods: BIA, SGA, BMI, and serum albumin (SA) levels were performed to assess malnutrition following liver transplantation. BIA measurement was used as reference standard to determine existing malnutrition. A phase angle (PA)
